The advertisement for donations shows the word "organization" spelled with a "S" instead of a "Z" as it should be. I understand that the English language, especially American English can be hard for non English speaking people.. But the use of a simple Spell-Check program can make your web site more professional looking by finding and correcting spelling mistakes. I mean no disrespect and only wish to help. Very respectfully, John Harrelson Carson City, NV USA
